I am interested whether ad.doubleclick.net ads are safe? Or are they dangerous? I have noticed that they appear on my computer screen sometimes, also I can see this URL flashing inbetween redirects when I click on web ads. ad.doubleclick.net ads show up frequently enough to annoy me. another question is, how can I stop these ads? I don’t want to see them anymore. How do I remove ad.doubleclick.net?
